ofdm系统matlab仿真研究，结合书本觉得很有用。(Simulation of the system matlab OFDM, combine the book feel useful.)

对于蒸发冷凝的相变UDF，给与大家参考,希望与大家多多交流(For evaporation condensation phase transition UDF, give your reference)

Support for SD detector

说明：  OFDM的基本框架搭建，实现OFDM技术的基本功用，适合于初学者(Build the basic framework of OFDM, OFDM technology to achieve the basic skills to use, suitable for beginners)

Communication Systems Lab 8

calculate the air properties(input the parameters are relative humidity and dry bulb, if you input the above parameter that you can get another air properties)

基于高斯混合模型，经由一种高效率的EM-MAP算法，解决图像超分辨率重建问题(A general framework for solving image inverse problems is introduced in this paper. The approach is based on Gaussian mixture models, estimated via a computationally efficient MAP-EM algorithm.)

计算任意多个信号源的信息熵，信道容量迭代算法，线性分组码(Calculation of any source of information entropy, channel capacity iterative algorithm for linear block codes)

说明：  针对均匀圆阵，在高斯白噪声环境下，仿真DOA估计性能。(For uniform circular array, the performance of DOA estimation is simulated in Gaussian white noise environment.)

软件程序按照发射端所掌握的各用户信道状态信息的程度共分为两部分：即完整信道状态信息(CSIT)和部分信道状态信息(CSIP)。其中，每一部分都包括预编码(precoding)和用户调度(scheduling) 在CSIT中，precoding又按照各用户的数据流数分为单数据流和多数据流两种情况。在每种情况下，首先考察了不同预编码算法的性能表现，包括两种ZF、MMSE、SINR、SLNR。之后又考察了功率分配算法的性能表现（文件名中含有PD表明其含有功率分配的过程）。按照不同指标进行功率分配的，在文件名中进行了区分，如PD_CN代表以信道范数为参考指标进行功率分配。Scheduling部分首先观察了RoundRobin、MaxH和MMSLNR三种算法的性能对比。之后在Kc和Round部分分别观察了不同预选用户数和不同最大替换轮数下MMSLNR算法的表现。 在CSIP中，只对各用户单数据流的情况进行了仿真。采用的预编码算法主要有DSLNR（即直接运用CSIT下的预编码算法）、ESLNR（即对SLNR进行均值计算的，在CSIP中，引入均值计算的与SLNR有关的算法，其文件名中都有modified以示区别）、EMMSE（即陈明老师那边的那篇文章中的预编码算法）。Scheduling中也只是简单的观察了RoundRobin、MaxH、DMMSLNR和EMMSLNR（前者没有均值计算，后者有）的性能对比。(The degree of channel state information for each user software program in accordance with the master transmitter consists of two parts : the complete channel state information (CSIT) and partial channel state information (CSIP). Wherein , each of which comprises a pre- coding (precoding) and the user scheduling (scheduling) In CSIT in , precoding and each user according to the number of data streams into a single data stream and multiple data streams in both cases . In each case , first examine the performance of different pre- coding algorithm, including two ZF, MMSE, SINR, SLNR. After they inspected the power allocation algorithm performance ( file name contains PD showed that it contained power allocation process ) . According to different indicators for power distribution , make a distinction in the file name , such as PD_CN representative channel norm-referenced index for power distribution . Scheduling section first observed the performance comparison RoundRobin, MaxH and MMSL)
